The baseA also comprises transverse bars +12, which are arrangedin'pairs above and paralflel to'the ba-r'sff. The bars 12 are secured to and supportedyfromthe bars 7 by brackets 13 which alsofunction to maintain the bars 7 as each endpfthe base 4 in relatively spaced relation, The bars 12 extend'beyond the harsTat one side of the base 4 to provide supporting elements 12 for a table 114. "Thetotver 5;"Which is'similar to the corresponding part oftheelevator disclosed in p i 5 said=-prior*patent, comprises standards 15 P e in accordance W-ith"the 5 m3 is a sectional t iew illustrating the oer which are arranged at one side of the base 4 and are secured at their lower end, as at 16, to the bars 6. Braces 17 extend from the upper ends of the standards 15 to the other side of the base 4, and are connected intermediate their ends to the standards by bars 18. A horizontal brace 19 and cross braces 20 are secured to and between the standards 15. Endless sprocket chains 21 extend longitudinally of the standards 15, and pass about drive sprockets 22 journaled in the lower ends of the standards and supporting sprockets 23 journaled on the upper ends of the standards. Idle sprockets 24 which are journaled in the standards 15 near the lower ends thereof, engage the inner runs of the sprocket chains 21.

Carriers 25 are secured to and extend right angularly from the sprocket chains 21, The carriers 25, during the movement of the sprocket chains 21, pass upwardly or downwardly through the slots 26 formed in and extending transversely of the table 14. During the use of the elevator for the purpose of stacking lumber being unloaded from cars, the carriers 25 pass upwardly through the table slots 26, and during the use of the elevator for the purpose of lowering lumber from the pile being loaded on to the cars, the carriers pass downwardly through the table slots. During the unloading of the cars, the lumber is deposited upon the table 14, and is picked up therefrom by" the carriers 25 and carried to the top of the pile being formed. During the loading of the cars, the lumber is taken from the pile and deposited upon the carriers 25, the carriers deposit the lumber upon the table, and the lumber is picked up from the table and placed upon the cars.

The sprocket chains 21 are similar to the sprocket chains disclosed in said prior patent, and the carriers 25 may embody the construction of either of the carriers disclosed in said patent. The sprocket chains 21 are adapted to be driven from an engine 27 mounted upon the base 4. The engine 27 may be of any suitable type. A shaft 28 which carries the drive sprockets 22, may be driven from the engine 27 by any suitable transmission mechanism, as suggested at 2", which will permit the sprocket chains 21 to be driven in a direction to pick up lumber from the table 14 or in a direction to deposit lumber upon the table. These means may be similar to that shown in said prior patent.

The table 14 comprises a middle section 14 which is arranged upon and fixed to the bars 12, and end sections 14 which are pivotally connected, as at 29, to the middle section. The table sections 14 are adapted, to be supported in alinement with the table section 14 by props 30. The props 30 comprise yokes 3O which are pivoted, as at 31, to the opposite sides of the free or outer ends of the table sections 14*. The props 30 also comprise rods 30 which extend downwardly from the yokes 30 and are adapted to engage the ground adjacent the track. The table sections 14 are adapted to be supported in an upright position with respect to the table section 14 when the elevator is not in use. After the table sections 14 have been swung into this position, the props 30 are swung into an inwardly extended position with re spect to the upper ends of the table sections, so as to permit the props to be engaged by hooks 32 which are connected as at 33, to the tower 5. The table sections 14 and 14 are provided with rollers34 which permit lumber to be shoved from either end of the table onto the middle section thereof.

Theelevator is supported by the car 1 for movement along the track, and when it reaches the place where the cars are to be unloaded or loaded, it is raised off of the car and supported in its raised position above the track. Means for raising theelevator and supporting it in its raised position, comprises foot bars 35 of angular formation and equal inlength to the corresponding dimension of the base 4. The foot bars 35 are arranged below the base 4 and outwardly of the rails 2,, and they are connected to the base by jack screws 36, The jack screws 36 are slidably mounted between the bars 7 and 12 and pass through openings 8 in the straps 8 which are secured to the lower sides of the bars7. Brackets 37 extend downwardly from the bars 7 and have angular lower ends 37 through which the jack screws 36 pass. The straps 8 support the jack screws 36 near their upper ends and the bracket ends 37 support the jack screws near their lower ends, with the result that the jack screws are connected to the base 4 in a substantial manner and for vertical adjustment with respect thereto. The jack screws 36 are arranged at the junctures of the bars 6 and 7 and their lower ends are turned inwardly, as at 36 to position the foot bars 35 above and close to the ends ofthe ties 3.

The jack screws 36 are adapted to be raised and lowered through the medium of nuts 38 which are engaged therewith and are ar ranged between and in contact. with the bars 7 and 12. The bars 7 and 12 hold the'nuts 38 against endwise movement, and the nuts are adapted to be turned through the medium of hand wheels 39 which extend centrally therefrom.

lVhen the elevator reach-es the place where the cars are to be unloaded or loaded, the nuts 38 are turned in a direction to move the foot bars 35 into contact with the ends of the ties 3, and thereafter they are turned in the same direction to raise the elevator 01? of the car 1. The el'eyator is now supported from the ties 3 and the car 1 is removed from beneath the elevator so as to permit the unloaded car to pass beneaththe elevator dur ing the unloading or loading operation. As

the unloaded cars maypass-beneath the elevator, the unloading or loading operation.

may be performed ina comparatively short time, in a comparatively easy manner, and at the expenditure of comparatively little labor. After the cars have been unloaded or loaded, the car 1 is moved beneath the elevator and theelevator lowered on .to the same by turning the nuts 38 in the reverse direction and, thereafter, the nuts are turned in the same directionto raise the foot bars above the ties 3. The elevatormay'now be moved along the track to another place where cars are to be unloaded or loaded. As the table sections l l are supported in upright position during the movement of the elevator from place to place along the track, they cannot contact with a pile of lumber opposite through the brackets and straps and through thespaces between the upper and lower bars,

nuts engaging thejack screws and arranged betWe-enthe lower and upper bars,the jack screws being provided with inturned lower ends, foot bars secured tothe lower ends of andbraces secured to the V the ack screws,
